The present invention relates to a jewellery stone (10), having a crown (12), a pavilion (13) and an intermediate part between said crown (12) and said pavilion (13), referred to as the girdle (14). It has metal fastening means (20) that are designed to allow it to be fastened to said mount, comprising a connecting zone (21) located on said pavilion (13). The connecting zone (21) is located on a part of or all of a limited-width peripheral sector (131) of said pavilion (13), in which incident rays (R3) on the crown (12) pass into the stone (10) through an air/stone interface, are either reflected by a first pavilion/air interface at a point of the pavilion (13) that is lower than said connecting zone (21), or are reflected entirely by said first pavilion/air interface of said stone (10) in the peripheral sector (131) having said connecting zone (21). |
